The push button box 10 according to the present embodiment is for instructing the operation of the pedestrian signal light device. Here, although not shown, the pedestrian signal lights are installed at both ends of the pedestrian crossing so as to be incidental to the vehicle signal lights installed at intersections and the like of general roads.

The push button box 10 is used by being fixed to a support such as a nearby telephone pole for each pedestrian signal light device. Specific operations such as the lighting color change and the timing thereof in the vehicle signal light device and the pedestrian signal light device are controlled according to a predetermined program of a traffic signal control device (not shown). Further, some of the functions of the push button box 10 are also controlled according to a predetermined program of the traffic signal control device. The vehicular signal light device, the pedestrian signal light device, and the push button box 10 are connected to the traffic signal control device via signal lines, respectively.

As shown in FIG. 1, the push button box 10 has a box-shaped housing 11 as a main body that houses various components such as electronic components and these units. The casing 11 is composed of a base body 20 which is the back side and which is open on the front side, and a front case 30 which is assembled so as to cover the opening of the base body 20 from the front and in which a push button 40 is arranged. In the present embodiment, two push buttons 40A and 40B are provided above and below the front case 30, and they are collectively referred to as push button 40.

In the push button box 10, the operation of the pedestrian signal light device is instructed by touching the push button 40. However, the operation here is not limited to the change of the lighting color (start of blue lighting), and other voice guidance or the like. Is also included. Further, as will be described later in detail, the push button 40 is composed of a capacitance sensor 45 that does not need to be pushed at the time of operation and can be operated simply by touching. Hereinafter, for convenience, the term “press” or “touch” is simply referred to as “operation”.

The base body 20 is a shallow case-shaped member having an opening on the front side, and is integrally formed from any material having excellent strength such as a metal material such as aluminum or a resin material such as AAS resin. More specifically, the base body 20 includes a vertically long rectangular rear portion 21, a horizontally long rectangular bottom portion 22 extending forward from the lower edge of the rear portion 21, and a little diagonally upward from the upper edge of the rear portion 21. The upper surface portion 23 and the side surface portions 24, 24 having a substantially right triangle surrounding the sides are formed, and the front surface side is open. Here, the upper surface portion 23 mainly constitutes the upper surface portion of the entire push button box 10, and the outer surface thereof becomes a rear inclined surface 23a which is inclined downward and obliquely rearward from the horizontal plane.

The outer surface of each surface of the base body 20 is a smooth flat surface without protrusions, and the corners where the two or three surfaces are joined are rounded to ensure safety. Further, the push button box 10 is fixed to a support such as a telephone pole, but the back portion 21 of the base body 20 has a band-like shape that is fixed at an appropriate height position of the support, for example, by hugging. A mounting bracket is provided. The rear surface portion 21 is preliminarily provided with a screw hole for fastening the mounting bracket. However, the specific mounting method of the push button box 10 is not particularly limited. It should be noted that the attachment position of the push button box 10 may be set in a range of height that is easy for a wheelchair or a child to operate.

The front case 30 is a shallow lid-shaped member which is opened at the back side and is aligned so as to cover the peripheral edge of the opening of the base body 20, and is integrally molded from the same material as the base body 20. More specifically, the front case 30 includes a front surface portion 31 that forms the front surface of the entire push button box 10 and side surface portions 32 and 32 that are substantially isosceles triangles that surround the sides of the front surface portion 31, and the rear surface side is open. .. Here, at least a part of the front surface portion 31 is formed as a front inclined surface 31a that is inclined downward and obliquely forward from the horizontal plane.

More specifically, the front surface portion 31 is formed such that the upper half side thereof is formed as a front inclined surface 31a that is inclined downward and obliquely forward from the horizontal plane, and the lower half side is formed as a front vertical surface 31b that is connected to the lower end of the front inclined surface 31a and hangs down. ing. The boundary between the front inclined surface 31a and the front vertical surface 31b is gently curved, and the outer surface of each surface of the front case 30 is smooth without any protrusions, and the corners where the two or three surfaces are joined are rounded. Considering safety.

As shown in FIG. 7, the housing 11 has a basic structure such that the front case 30 on the front side covers the opening of the base body 20 on the back side from the front (back opening type). That is, the front case 30 is attached to the base body 20 so as to be fitted obliquely from above. Here, the seam of the opening peripheral edge along the upper surface portion 23 of the base body 20 and the upper end edge of the front surface portion 31 of the front case 30 that covers the opening peripheral edge from the front is at least a part of the upper surface portion of the entire housing 11. It is arranged on a certain rearward inclined surface 23a.

Thus, the opening on the back side of the front case 30 is aligned with the opening on the front side of the base body 20. More specifically, as shown in FIGS. 8 and 10, a convex portion 20 a extending as a ridge is formed along the peripheral edge of the opening of the base body 20, while a concave portion extending like a groove along the peripheral edge of the opening of the front case 30. 30a is formed. Here, the convex portions 20a are engaged with each other in the concave portions 30a and are combined with each other. An annular packing 30b made of an elastic body is inserted into the bottom of the recess 30a so that the projection 20a is pressed against the recess 30a to enhance waterproofness. As an opposite form, the concave portion may be provided on the base body 20 side and the convex portion may be provided on the front case 30 side.

As shown in FIGS. 7 to 10, among the opening peripheral edges of the front case 30, the opening peripheral edge of the base main body 20 is provided at the upper end edge of the front surface portion 31 (the front inclined surface 31 a thereof) and the rear end edge of each side surface portion 32. The flange 30c is formed so as to cover not only the above but also the peripheral edge of the opening of the base body 20 from above. The edge of the flange 30c is actually the seam of the front case 30 with respect to the base body 20, and in particular, the flange 30c (the seam) along the upper edge of the front surface portion 31 of the front case 30 is as described above. It is arranged on the rear inclined surface 23a. It should be noted that there is no flange 30c at the lower edge of the front surface portion 31 (the front vertical surface 31b thereof). That is, there is no step or edge at the joint between the lower edges of the openings of the base body 20 and the front case 30.

In this way, the base body 20 and the front case 30 are combined and screwed together to form a so-called rear opening type housing 11. Although not shown in the drawing, various components such as electronic components and these units are housed in the internal space of the housing 11. The screw 30d for fixing the front case 30 to the base body 20 is provided not on the upper surface side of the base body 20 but on the front surface side of the front case 30. More specifically, screw holes are provided at the four corners of the front surface portion 31 of the front case 30, and screw holes are also provided at the matching positions on the peripheral edge of the opening of the base body 20. As the screw 30d to be screwed into these screw holes, for example, a special screw that is difficult to remove unless a dedicated tool is used to prevent mischief may be used.

On the front side of the front case 30 in which the screw 30d is arranged, the inclination angle is closer to vertical than the upper surface, so that water droplets do not stay and it is possible to more reliably prevent water from entering through the screw hole. Further, since the tool can be tightened and removed from the front of the push button box 10 with a tool, the support body to which the push button box 10 is fixed does not interfere with the work, and the front case 30 can be easily removed to remove the case 11 from the front case 30. It is possible to check and maintain the inside of the. As shown in FIG. 11, the recesses 30a into which the packings 30b are fitted along the peripheral edge of the opening of the front case 30 are arranged so as to be located inside the screw holes at the four corners thereof, and the waterproofness is enhanced.

As shown in FIG. 1, the front case 30 is provided with two push buttons 40A and 40B in the present embodiment. One push button 40A is formed on the front inclined surface 31a that is the upper half side of the front surface portion 31, and the other push button 40B is formed on the front vertical surface 31b that is the lower half side surface of the front surface portion 31. Since the front inclined surface 31a is located at a position or direction that is easily touched by a visually impaired person, the push button 40A on the front inclined surface 31a is set especially for the visually impaired person. Further, the push button 40B on the front vertical surface 31b is set for a normal person or an elderly person. Note that the number of push buttons 40 is not particularly limited, and only one or three or more may be provided at any arbitrary position regardless of the inclination of the front surface portion 31.

As shown in FIG. 7, in detail, the push button 40 includes an operation surface portion 41 that protrudes in a stepwise manner and spreads in parallel to a reference surface of a portion arranged on the outer surface side of the front surface portion 31. The operation surface portion 41 spreads in a rectangular shape, and its peripheral edge is a rounded step. The operation surface portion 41 is arranged so as to cover the circular holes 33 provided on the front inclined surface 31a and the front vertical surface 31b of the front surface portion 31 from the outer surface side, and the back side of the operation surface portion 41 is the inner surface side of the front surface portion 31. It is screwed from. The operation surface portion 41 is not mechanically movable, and is fixed to the outer surface side of the front surface portion 31 so as not to move. An annular packing 42 made of an elastic body is attached along the peripheral edge on the back side of the operation surface portion 41 so as to be pressed against the outer surface of the front surface portion 31 to enhance waterproofness.

Inside the operation surface portion 41, a rectangular spacer 43, which is slightly smaller, is provided. The spacer 43 is made of a thin metal plate made of metal such as stainless steel or iron, and has a stepped contact portion 43a on the back side thereof, which projects through the hole 33 to the inner surface side of the front portion 31. .. A capacitance sensor 45 is attached to the inside of the front surface portion 31 via a support case 44 screwed to surround the hole portion 33.

The capacitance sensor 45 detects a capacitance change of an electrode when an object approaches the detection electrode and performs an ON operation. Since the configuration is general, detailed description thereof will be omitted. The contact portion 43a of the spacer 43 is in contact with the detection electrode of the capacitance sensor 45. That is, the metal spacer 43 expands the sensing area of the capacitance sensor 45. The contact portion 43a of the spacer 43 is inserted through the hole portion 33 of the front surface portion 31 and the hole portion 44a having a smaller diameter provided in the support case 44. The hole portion 44a is larger than the entire size of the capacitance sensor 45. Since the diameter is also small, there is no possibility that the sensor will be taken out through the hole.

On the planar surface of the operation surface section 41, a pictogram 41a that indicates operation guidance and next action is displayed. As a concrete design of the pictogram 41a, as shown in FIG. 1, the upper push button 40A is designed mainly for visually impaired persons so that the visually impaired person hears a guide sound from a speaker 60 described later. However, the scene is crossing a pedestrian crossing. In addition, the lower push button 40B simply expresses a pedestrian crossing mainly for normal people.

A side surface seal 24a on which a pictogram is displayed is also attached to the outer surface side of each side surface portion 24 exposed to the outside in the base body 20 as needed. Further, a Braille nameplate 38 for visually impaired persons may be arranged above the push button 40A in the front surface portion 31 of the front case 30.

As shown in FIG. 1, the front case 30 is provided with a display unit 50 that displays various kinds of information regarding the operation of the pedestrian signal light device. The display unit 50 is arranged along the curved boundary between the front sloped surface 31a and the front vertical surface 31b in the front surface unit 31, and has a horizontally long position where the display surface of the display unit 50 is exposed to the outside. A rectangular opening 34 is provided. The display section 50 is fixed from the inner surface side of the front section 31 in a state where the display surface thereof matches the opening section 34. Here, the specific type of the display unit 50 is not particularly limited, but in any form such as a liquid crystal unit or an LED display, characters or figures are displayed as various information on the display surface. Anything is possible.

The display unit 50 corresponds to the lower push button 40B of the two push buttons 40 and is not only arranged immediately above (next to) the push button 40B, but also on the outer surface of the front face portion 31 with a narrow groove. They are housed in the same frame 35 partitioned by and are more clearly associated with each other. The inside of the frame 35 may be painted in a color different from that of the front case 30 to strengthen the association. The angle of the display surface of the display unit 50 is inclined parallel to the joint (the rear end edge of the side surface portion 32) of the front case 30 with respect to the base body 20.

Various functions of the push button box 10 including the display of the display unit 50 are controlled by a predetermined program of a control board housed in the housing 11 in addition to the traffic signal control device described above. The control board is composed of a microcomputer including an ordinary CPU, RAM, ROM, interface, etc., and is used for electronic parts such as the capacitance sensor 45 of the push button 40 and a speaker 60 described later, in addition to the display section 50. It is connected via wiring.

In the present embodiment, the display unit 50 corresponds to the lower push button 40B, and is controlled to display only when the push button 40B is operated. In this way, the display unit 50 may be set to be displayable in association with the operation of one or a plurality of push buttons 40. As specific display contents of the display unit 50, for example, in order to inform that the push button box 10 is in a sensitive state based on the operation of the push button 40B, a character such as "please wait" or a pedestrian traffic light Various information regarding operation is applicable.

The display unit 50 is normally in the off or non-display state, but when the push button 40B is operated, the display unit 50 lights up until the lighting color of the pedestrian signal light device changes from red to blue. , Such as "Please wait" is displayed. As various information, for example, "waiting time" of the pedestrian traffic light may be displayed. That is, when the pedestrian traffic light is red, it is conceivable that the waiting time from the time when the push button 40 is operated to the time when the pedestrian traffic light is red is subtracted and displayed as a digital number. In addition, the display unit 50 may display the place name of the current location, the current time, the weather forecast in the near future, and directions (main building names in the traveling direction) and the like.

Further, the push button box 10 includes a speaker 60 that outputs a sound regarding the operation of the pedestrian signal light device. The speaker 60 is conventionally arranged on the control board, but in the push button box 10 according to the present embodiment, the speaker 60 is arranged not on the control board but on the front case 30. That is, as shown in FIG. 7, a mounting portion 36 is provided on the inner surface of the front portion 31 of the front case 30 where the speaker 60 is arranged so as to surround the outer periphery of the speaker 60 from both sides. .. Here, the attachment portion 36 may be integrally formed when the front case 30 itself is formed.

As shown in FIGS. 13 to 16, the speaker 60 is fixed to the mounting portion 36 via a plate-shaped bracket 61 that covers the speaker 60 from the rear side in a state where the speaker 60 is positioned on the mounting portion 36 on the inner surface side of the front surface portion 31.

Further, the bracket 61 is also separately screwed to the inner surface side of the front surface portion 31.

The speaker 60 is supported by the mounting portion 36 so that the cone paper on the front surface side is inclined and separated from the inner surface of the front portion 31, and the front portion 31 facing the cone paper is for outputting sound to the outside. A small hole 37 for passing sound is provided. The small hole 37 is arranged at a position hidden inside the operation surface portion 41 of the push button 40B. The cone paper of the speaker 60 is preferably water resistant. The bracket 61 is made of a metal plate such as stainless steel or iron processed into a rectangular shape having an area that can cover the entire speaker 60 when viewed from the rear.

From such a speaker 60, when the push button 40 is operated, a predetermined sound notifying that the push button 40 has been operated and a voice message of "please wait" are output, and the push button box 10 is for the visually impaired. Alternatively, a predetermined sound for notifying the location of the push button box 10 may be constantly output. Sounds and voices from the speaker 60 are controlled by a predetermined program of a control board housed in the housing 11 in addition to the traffic signal control device described above.

FIG. 17 schematically shows how the push button box 10 according to the present invention has reached the design. FIG. 17A schematically shows the conventional pushbutton box 1 shown in FIG. 20. As described above, a box-shaped casing having a large front side opening and a front opening of this casing are shown. This is configured as a so-called front opening type by a flat plate-shaped lid that covers the inside. 17B, the front side and the back side of the front opening type structure of FIG. 17A are reversed, and the front side front case on which the push button is arranged is used to move the front side opening of the rear side base body forward. It shows a basic structure of a so-called back opening type that covers from the above.

The basic structure of the back opening type shown in FIG. 17(b) is similar to that shown in FIG. 17(a), and a vertically long rectangular box type is used as a basic shape. In this way, by inverting the overlapping of the front side and the back side of the housing, all the edges that are the opening peripheral edges are arranged on the back side. Therefore, it is possible to prevent a pedestrian from being injured due to the front surface of the edge being exposed, and the conventional eave-shaped edge portion 5 (see FIG. 20) does not exist, so that peeling off of coating or rusting from the portion can be prevented. ..

FIG. 17(c) shows the case itself, which is different from the structure of the rear opening type shown in FIG. 17(b), in order to further prevent foreign objects from being placed on the upper surface of the case and to improve the operability of the visually impaired. By inclining, the button installation surface (operation surface) is inclined downward obliquely forward from the horizontal plane. According to this structure or arrangement posture, the front case covers the opening of the base body from the front side, and the rear side opens downward obliquely rearward of the housing.

In FIG. 17D, a rear surface and a bottom surface are added to the base main body side in consideration of mounting to a telephone pole or the like and mounting of piping to the rear opening type structure of (c). As shown in the figure, the back surface of the base body is a vertical plane in consideration of the installation on the utility pole, and the bottom surface of the base body is a horizontal plane in consideration of the piping installation. .. In addition, by bending the front case up and down and installing the push button for the visually impaired person on the inclined upper surface, the convenience of the visually impaired person is not impaired even if a plurality of buttons are installed.

In the push button box 10 according to the present embodiment, the housing 11 as a whole can be thinned by inclining the joint between the base body 20 and the front case 30. More specifically, as shown in FIG. 18, in the case where the front case is provided with an inclined upper surface, FIG. 18A shows a structure in which the joint between the base body and the front case is inclined, and FIG. It shows a structure in which the joint is vertical.

As can be seen from the comparison between FIGS. 18A and 18B, when securing the same inclined surface and the same bottom surface, it is possible to reduce the thickness as a whole by inclining the joint. That is, as shown in the figure, the inclined surfaces of (a) and (b) have the same length and the same angle, and the bottom surfaces of (a) and (b) also have the same length. The thickness a of () is smaller than the thickness b of (b). Further, in (a), the plane portion of the upper surface is also eliminated.

The reference items of the push button box 10 have been supplemented above, but next, the specific operation of the push button box 10 according to the present embodiment will be described.
As shown in FIGS. 1 to 7, according to the present push button box 10, its housing 11 is a combination of a base body 20 that is a back side and an opening on the front side, and a base body 20 that covers the opening of the base body 20 from the front. And a front case 30 on which the push button 40 is arranged.

According to such a rear opening type structure, although the outline has already been described, the opening peripheral edge of the base body 20 is hidden by the front case 30, and the opening peripheral edge (edge) of the front case 30 is usually human hand. It is arranged on the back side that is not touched, and on the front side of the entire housing 11, it is possible to minimize the protrusions that appear on the outer surface thereof. Therefore, the pedestrian can be prevented from being injured, and the conventional eave-shaped edge portion 5 (see FIG. 20) does not exist, so that the peeling or rusting of the coating from the portion can be prevented.

In particular, the front case 30 has a rear surface that opens downward and obliquely rearward of the housing 11 in a state of covering the opening of the base body 20 from the front. As a result, rainwater and dust are less likely to enter from the seam where the opening edge of the front case 30 overlaps the opening edge of the base body 20 and the outside thereof, and it is possible to more reliably prevent peeling and rusting of the coating. it can.

Moreover, among the opening peripheral edges of the front case 30, the upper end edge of the front surface portion 31 and the rear end edges of the side surface portions 32 are simply aligned with the opening peripheral edge of the base body 20 as shown in FIGS. Instead, there is an overlapping flange 30c so as to cover the opening peripheral edge of the base body 20 from above. As a result, the waterproof property can be further enhanced, and it is possible to prevent a mischief such as prying open with a tool such as a flat-blade screwdriver.

Further, as shown in FIGS. 7 and 8, the flange 30c serving as a joint of the front case 30 with respect to the base body 20 is inclined downward and obliquely rearward from the horizontal plane as at least a part of the upper surface of the housing 11. It is arranged on the rear inclined surface 23a. As a result, even if the seam is arranged on the upper surface of the housing 11, the rainwater and dust do not stay along the seam because the seam is located on the rear inclined surface 23a. Moreover, foreign matter cannot be left on the rearwardly inclined surface 23a due to the inclination.

As shown in FIG. 1, the front case 30 has a front inclined surface 31a formed on the upper half side thereof, and a front vertical surface 31b formed on the lower half side thereof so as to extend downward from the lower end of the front inclined surface 31a. Since the front inclined surface 31a is located at a position or direction that is easily operated by a visually impaired person, a push button 40A for the visually impaired person is provided on the front inclined surface 31a. As a result, the visually impaired person can naturally touch the push button 40A at the position where the hand is just extended, and the operability is improved.

On the other hand, a push button 40B for a healthy person is provided on the front vertical surface 31b. Since the push button 40B on the front vertical surface 31b is at a particularly low position, it can be easily operated by a child or an elderly person. In this way, the two push buttons 40A and 40B can be used separately for each user. Further, since the seam between the base body 20 and the front case 30 is inclined, the overall thickness of the housing 11 can be reduced, and the degree of freedom in designing the front case 30 is also improved.

As shown in FIG. 7, each of the push buttons 40A and 40B has an operation surface portion 41 that extends in parallel with a reference surface of a portion arranged on the outer surface side of the front case 30 in a stepwise manner, and the operation surface portion 41 of the operation surface portion 41. It is provided with a metal spacer 43 arranged inside, and a capacitance sensor 45 arranged inside the front case 30 in a state of being in contact with a part of the spacer 43. According to the push button 40 having such a configuration, a visually impaired person or the like can easily feel it and operate it, and durability and strength can be improved as compared with the conventional general button structure. Further, in the conventional push button, the sensor itself is generally covered with a cover, but since the capacitance sensor 45 is provided inside the housing 11 and is not exposed to the outside, damage due to mischief is also prevented. be able to.

Even if the capacitance sensor 45 is inside the housing 11, the detection electrode of the capacitance sensor 45 is in contact with the contact portion 43 a of the metal spacer 43 through the hole 33 of the front surface portion 31. Here, since the spacer 43 is covered with the operation surface portion 41 but is spread out in a thin plate shape on the outer surface of the front surface portion 31, the sensor can be sensed in a wider area than the detection electrode of the capacitance sensor 45. ..

According to such a capacitance type sensor, there is no possibility that the sensor will become inoperable due to freezing in a cold district unlike the mechanical button structure. Further, since the inner diameters of the front surface portion 31 through which the contact portion 43a of the spacer 43 is inserted toward the inside and the hole portions 33 and 44a of the support case 44 are smaller than the entire size of the capacitance sensor 45, the operation surface portion 41 comes off. However, there is no possibility that the capacitance sensor 45 will be taken out through the holes 33 and 44a.

Further, on the surface of the operation surface section 41, a pictogram 41a that indicates operation guidance and next action is displayed. According to such a pictogram 41a, the function at the time of operating the push button 40 is replaced with a character by a unique pictogram representing "person" and "function" instead of the conventional symbol mark representing "person". Anyone can understand intuitively.

The pictogram 41a may be directly printed on the surface of the operation surface portion 41, but if it is configured such that a printed thin metal plate such as aluminum is attached, the sensitivity of the capacitance sensor 45 can be further enhanced. .. The specific shape of the operation surface portion 41 is not limited to the rectangular shape shown in the figure, and various shapes can be easily designed. Further, although the operation surface portion 41 is a molded product of synthetic resin, each push button 40 may be molded or coated with a resin of a different color.

When the push button 40 is actually operated, the capacitance sensor 45 senses and outputs an ON signal to the traffic signal control device. When the traffic signal control device receives this ON signal, the traffic signal control device switches the lighting color of the pedestrian signal light device from red to blue after a lapse of a predetermined time. Further, the control board inside the housing 11 controls the display of the display unit 50 based on the ON signal from the capacitance sensor 45 of the lower push button 40B. When the lighting color change of the pedestrian signal light device is completed, the display unit 50 returns to the off or non-display state.

On the display unit 50, as described above, various information related to the operation of the pedestrian traffic light device, such as the word "Omachimasu", which informs that the push button box 10 is in the sensitive state based on the operation of the push button 40B, is displayed. Is displayed. Here, the corresponding language for the character information is not limited to Japanese, but character information in a plurality of languages such as English and Chinese may be set in the ROM of the control board in advance. Further, as described above, the display unit 50 can be displayed in conjunction with the operation of one or a plurality of push buttons 40, and the display by the display unit 50 can be associated with the operation of a specific push button 40. It is possible to omit unnecessary display.

Further, the push button box 10 includes a speaker 60 that outputs a sound or a sound related to the operation of the pedestrian signal light device. As for the arrangement of the speaker 60 in the housing 11, it is attached to the inner surface side of the front case 30 without arranging it on the control board as in the conventional case. That is, as shown in FIG. 13, a mounting portion 36 is provided on the inner surface side of the front case 30 where the speaker 60 is arranged, and the speaker 60 is positioned on the mounting portion 36 to cover the speaker 60 from the rear side. The speaker 60 is screwed to the mounting portion 36 via the bracket 61 of.

According to such a mounting structure of the speaker 60, the dead space on the inner surface side of the front case 30 can be utilized as an arrangement space, and the mounting work becomes easy. Further, when the speaker 60 is fixed on the control board via the bracket, it is difficult to secure a space for disposing the speaker 60. However, by effectively utilizing the dead space, it is possible to mount speakers of various sizes and shapes. Become.

The back side of the speaker 60 is covered with a plate-shaped bracket 61 over the entire area. Therefore, as in the case of simply supporting a part of the back side of the speaker 60 with a T-shaped sheet metal, sound does not escape from the gap of the sheet metal to the back side (inside the housing 11), and a sufficient sound pressure is obtained. Can also be secured. A small hole 37 for sound passage is provided in the front surface portion 31 of the speaker 60 facing the cone paper on the front surface side. The small hole 37 is hidden inside the operation surface portion 41 of the push button 40B. Therefore, there is no possibility that rainwater or the like will enter the inside of the housing 11 through the small holes 37.

As described above, the speaker 60 outputs a voice message such as "please wait" to inform that the push button box 10 has become responsive based on the operation of the push button 40. A predetermined sound for notifying that it is the button box 10 and the location of the push button box 10 is output. Sounds and voices from the speaker 60 are controlled by a predetermined program of a control board housed in the housing 11 in addition to the traffic signal control device described above. It should be noted that the voice information is not limited to Japanese, but it is better to prepare it in a plurality of languages such as English and Chinese.

By the way, in the case where there are a plurality of variations corresponding to, for example, visually impaired persons, healthy persons, elderly persons, etc., as functions of the push button box 10 in general, not limited to voice output by the speaker 60 and display by the display unit 50, these The function may be designed so that it can be realized by one control board, and can be appropriately selected by switching the switch on the control board. Furthermore, it is advisable to appropriately add, to the control board, for example, a function of automatically operating by receiving a radio wave from a predetermined transmitter carried by an elderly person or a disabled person.
